Attentional window and attentional capture 1 THE SIZE OF AN ATTENTIONAL WINDOW MODULATES ATTENTIONAL CAPTURE BY COLOR SINGLETONS
It has been proposed that during visual search a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local shape (focused attention) before starting the search for a non-singleton target. We demonstrate that increa...

Researchers have proposed that during visual search, a color singleton cannot capture attention in a bottom-up fashion (Jonides & Yantis, 1988). In the present study, we manipulated the size of the attentional window by asking participants to detect either a global (diffuse attention) or a local (focused attention) shape before starting the search for a nonsingleton target. We demonstrate that ...
متن کاملBreaking through the attentional window: capture by abrupt onsets versus color singletons.
Theeuwes (Psychonomic Bulletin & Review 11:65-70, 2004) proposed that stimulus-driven capture occurs primarily for salient stimuli that fall within the observer's attentional window, such as when performing a parallel search. This proposal, which is supported by some studies, can explain many seemingly discrepant results in the literature. The present study tested this proposal using a modified...
متن کاملExpectancies modulate attentional capture by salient color singletons
In singleton feature search for a form-defined target, the presentation of a task-irrelevant, but salient singleton color distractor is known to interfere with target detection [Theeuwes, J. (1991). Cross-dimensional perceptual selectivity. Perception & Psychophysics, 50, 184-193; Theeuwes, J. (1992). Perceptual selectivity for color and form. Perception & Psychophysics, 51, 599-606]. The prese...
متن کاملAttentional and oculomotor capture by onset, luminance and color singletons
In three experiments we investigated whether attentional and oculomotor capture occur only when object-defining abrupt onsets are used as distractors in a visual search task, or whether other salient stimuli also capture attention and the eyes even when they do not constitute new objects. The results showed that abrupt onsets (new objects) are especially effective in capturing attention and the...
